    Hi
    I will be replacing a single radiator with a double radiator in the near future. I have taken radiators off and replaced them in the past so it will hopefully be OK to do it. I am looking to replace with a rad of the same height and width. One thing I will obviously need to do is to fit blocking plug and bleed plug at top of rad. No problem as these are supplied with the new radiator.
    However, the existing rad has a TRV fitted. As I need to purchase and fit tails to the new rad, do these have to be specific to the TRV or can I use a generic 'tail'? I have researched this online but cannot find a definitive answer one way or another.
    Thanks in anticipation of any reply.

    Are the existing ones no good?

    Usually generic, any photos?

    I have no photos as the site is my son's house some 200+ miles away (going there in a week or so). As far as using existing tails from old rad, I read somewhere not to do it as they are 'old' and may be difficult to separate?

    They should be ok to reuse, they will be the same age as the valves and you are reusing them after all..

    Many thanks for that. Just for my information, do the tails contain 'anything' required in the operation of the TRV? I wouldn't have thought so but just asking.

    No, just bog standard tails, nothing special.

    For example, the ones below are not generic and "normal" tails won't do. If you use the existing ones you can be sure they will fit.
